lightweight rotors in sync with the cooled front plate (other thread i can't find or name) would be totally sick. and if im ever taking apart my s.c u can best believe i'm plugging the silencer holes!

 

Don't....

It's not worth it.

Read the entire thread (not just the first page) below, and make up your mind. Increased whine is not worth the risk of a plug falling out and destroying your rotors. It has happened to a few members on here.

Sub'd for final results

 

take a lot of time and weld them shut with plenty of cool time/ice/water to minimize any possible warpage

 

ice and water? no you would want to strip the whole case and heat the main case in the oven to 500-700*F (ish) and then weld it quickly. Then put it back in the oven to cool very slowly. Then send it out to get solution heat treated and hope that the heat treat doesnt warp it. Of course to do that you would need to know the exact alloy and the exact heat treatment it had before you welded the heat treatment away.

 

I don't think the case is heat treated. The rotors maybe, but not the housing.

It could be carefully welded with controlled heat, but it would be a mission and not worth it from what the research tells us, it just doesn't gain anything except noise.

Then again, I machined plugs to fit the holes and epoxied them in and had positive results, which was much easier than any welding.

 

U machined plugs? thats really cool! is it really louder now? sorry to bring this thread off topic

 

Best thing about those plugs is that they wont fit though the cores. Those cores catch practically every thing.

 

Same as any other method, but they can't go inwards and hit the rotors and damage the blower. Or if they were to somehow come out they would just get stuck in the manifold and not hit anything useful.
Yeah, including anything you happen to drop in the manifold while working on the car. Sucks to fish stuff out of there.

 

Subd....

 

would be nice to see a set of plugs made that had a flange on the bottom side, and 2 holes in them. put em in the blower, drill and tap 2 holes, put screws in there with green threadlock and they will never come out.

 

CRAP! I would go for it.

 

Cause I have 2.9 pulley on my M62 and I would want that Rotors in mine. Then it will be pointless to buy TVS Supercharger for 2 grands.

 

I need posted gains before I spend $500. Thatll almost get you a euthanasia head

 

this

 

You guys have to keep in mind that Steig's primary market is blown V8s. The gains that might be made on our tiny little M62s are miniscule to the larger blowers that the V8s run.

There are much cheaper and easier ways to make more hp on the LSJ.

 

im thinking ill build my head over the next year, hopefully by then some of you will have tried these and i can weigh it in my head on viable or not

 

^^^^ This! People get lost in the suggested gains that the 112's on v8's make and forget that our blower and motor is half the size. Our gen 5 blowers are more advanced than the 112's. More balanced and I believe a tighter twist than the 112's.

 

0* twist-2 lobe old school original style

60* 3 lobe eaton gen I-V(might have been genII or genIII even, i cant remember)

160* 4 lobe eaton gen VI

no matter what size blower they made, same rotor style from what i understood

 

twist is a big issue tho when boreing them out.

 

your high just because you have a hollowed rotor wont make even come close to the performance of a tvs

and this is one reason why the aftermarket wont do **** for this platform to many candy asses afraid to step up and try new things

 

hey guys i work with these style rotors all the time. with aircraft started motors and stuff. the lighter rotor will rev faster, and stay cooler while helping produce more power. my guess is that they are stock rotors that have been drilled. its a pretty simple process actually.

 

we already figured that out that they are stocl cores

 

My paying a whole lot for rotor machining isnt going to up the aftermarket

 

no it wont but the main reason we dont have much aftermarket support is because the people who own this platform wont step up and try somthing without proof all they hollar is proof of gains well those people need to get out and get their proof and quit waiting somone else to do it for them
